Hybrid heat pump technology requires dedicated state subsidies to drive the decarbonisation of the heating sector, according to specialists at the HHIC. Current policy focus on pure electric heat pumps overlooks a more pragmatic middle path that combines gas boiler and heat pump systems.
The sector sees hybrid systems as technically superior for retrofit applications, particularly in existing buildings where electric-only solutions face constraints. Installation costs and grid capacity issues make the blended approach more viable for many building operators.
Building services engineers argue that policymakers must recognise the practical limits of rapid full electrification. Without explicit incentive schemes for hybrid installations, the transition will stall in retrofit markets where pure heat pumps struggle with economics and infrastructure compatibility.
The gap between ideal decarbonisation pathways and on-site feasibility is widening. Without policy adjustment, many facility managers will delay investment decisions entirely rather than commit to either approach.
